shekhar deshpande  (10 years ago)

answer is 36
let us first see the no. with square less than 50
1*1=1,2*2=4,3*3=9,4*4=16,5*5=25,6*6=36,7*7=49
so now we need to get sum of squares to be 50 and also to choose the largest integer so
let's try 17,1+49=50 but its surely not the largest
now try 345,9+16+25 but still there is largest integer
now try 1236,1+4+9+36 and you got the answer
now product of digits 1*2*3*6=36.

ans:36 the digits are 1,2,3,6 so addition of these squares is 50 and right is always greater than left

The correct answer will be 25

because 5^2 + 5^2 = 50

and also 5*5 = 25 (in this 2 is in left side which is small and 5 is in right side which is larger than left side)
